Bug of the Week: The Mix Unscrambled

Last week I gave you two photographs that were teeming with insects. Many of you recognized the orange-yellow bumps were aphids.

Okay, it is very small, but between the legs of the butterfly is a newly hatched caterpillar. See the little guy with the black head at the arrow tip? It is a monarch butterfly caterpillar.

In this video, you can see one hatching under a microscope. (Video has music).

Another insect is hidden within those dark-colored aphids.

See the ones that are black or dark red? They are parasitized, which means they are carrying a tiny wasp larva inside them.

Eventually the dark aphids will stiffen and cling to the stem. In that stage they are called an aphid mummy. After a few days the larvae inside will complete its life cycle, pupate and then emerge as an adult wasp.

You can see where a wasp emerged from this aphid mummy through the round hole in the back.

Here’s the tiny wasp that emerged from the hole. She will lay her eggs in yet more aphids, resulting in yet more aphid mummies.

Finally, there is one other interesting thing about this picture. See that the butterfly has its mouthparts extended? I watched this butterfly for several minutes before taking its picture. It was sucking up the honeydew from the aphids.

We got to see all this because we planted a special plant in our yard. Do you have any plants that attract insects in your yard?
